I am enquiring about the rotors as mine sounds bad on idol, if I bought the lightweight rotor pack which Mace offers will it be as easy for me to just slide the old rotors out and put new ones in without taking the charger off?

if you're referring to our M90 LIGHTWEIGHT ROTOR PACK, as shown in the link below, then the installation process you've suggested is correct with the exception of re-greasing the rear needle roller bearings in the back of the supercharger
